[QUOTE="ytradio, post: 440736, member: 19779"] Yeah, this may be a problem. In 1990 it should have been an R12 system. R12 is outrageously expensive now if it can even still be obtained. A local friend of mine who does all my ac work had told me in the past that the systems that used different refrigerants are not compatible with one another. In other words, if I wanted the ac in my old Camero to work I was going to have to change to a new type R134A system. That was years ago, and I believe that system is also obsolete. [/QUOTE]
